A Protestant Air focuses on the Protestant connection linking three intellectual giants of twentieth-century French thought: Andre Gide, Jean-Paul Sartre, and Roland Barthes. All three came from a Protestant background and thus shared a common marginality in a nation culturally marked by Catholicism, one that profoundly shaped their personalities, thinking, and literary careers. When Andre Gide received the Nobel Prize in 1947, he declared that if he had represented anything as a writer, it was the "spirit of protestation." Clementine Faure-Bellaiche explores the filiation that this spirit weaves between Gide, Sartre, and Barthes. She shows how their Protestant difference, confronted with France's Catholicity, informed their posture as writers, their conceptualization of literature, and their elaboration of the figure of the French intellectual as a counter-authority, with a distinctive positioning vis-a-vis the individual and the institution. In so doing, A Protestant Air examines the religious underpinnings of twentieth-century letters and politics, their interaction with the secularization of French society, and, more broadly, the historical and philosophical relationship between the Protestant ethos and modernity itself.
